MOLDED POLYMERIC ARTICLE WITH LOW HAZE AND HIGH CLARITY

摘要

The present disclosure provides a molded article composed of a polymeric composition and processes for producing the same. The polymeric composition includes from about 60 wt % to about 99 wt % of a matrix of a propylene-based polymer. The propylene-based polymer has a refractive index (nl). The polymeric composition also includes from about 40 wt % to about 1 wt % of elongated elastomer particles dispersed in the propylene-based polymer. The elongated elastomer particles have a refractive index (n2). The propylene-based polymer and the elongated elastomer particles exhibit a refractive index mismatch whereby | nl n2 | > 0.002. The molded article has a haze value less than about 20% and optionally a viscosity ratio (VR) greater than 0.28.
